# ASCII Grid
# The Geotk implementation of ASCII grid reader is slight extension of the standard format,
# in that it can skip comment lines like those ones, accept the '=' and ':' characters as a
# separator between the key and the value, and can parse floating point values (not just
# integers).
#
# NOTES:
#  1) The actual cell size should be approximatively (2000, 620), but this format supports
#     only square pixel. Consequently the referencing in this file is wrong, but this is
#     okay for the purpose of our test suite.
#
#  2) The MIN_VALUE and MAX_VALUE attributes are Geotk extensions.
#     They are optional, but quite helpful when present.
#
#  3) The '=' character used below is not standard.
#     It is presents in this file for testing purpose only.
